Many users feel that the refrigeration effect of their refrigerated trucks is not very satisfactory. This leads to some matters that need to be paid attention to during the use of the refrigerated truck refrigeration unit. If the use is not standardized, the refrigeration effect will not achieve the expected effect.
1. The empty refrigerated truck needs to be pre-cooled for 20 to 30 minutes before loading. Because the function of the refrigerated unit is to maintain the temperature when the goods are loaded, rather than lowering the temperature, it is necessary to perform pre-cooling in advance to remove the stranded in the carriage. Heat to prevent loss of goods due to temperature differences.
2. The unit should stop working during loading and unloading. If the refrigeration unit is always working during loading and unloading, the air pressure inside and outside the compartment will be inconsistent, accelerating the hot air into the compartment, causing the temperature of the compartment to rise faster, and temporarily stopping the cooling unit When working, the wind pressure inside and outside the compartment is the same, and the speed of external hot air entering the compartment will be correspondingly slower.
3. There must be a gap between the goods and the four walls of the container. A refrigerated truck basically only has one refrigeration device. There is a gap between the goods and the container, which can better ensure the cold air flow inside the container and avoid the container. There is a temperature difference inside to prevent damage to the goods placed far away from the refrigeration device.
4. Avoid long-term exposure of refrigerated trucks under working conditions. Refrigerator truck box panels are generally made of composites. Under strong light exposure, it is easy to cause qualitative changes in the polyurethane glue inside the box panels, resulting in bulging. Running the refrigeration unit under strong light will not only cause greater damage to the unit, but also The ideal refrigeration effect cannot be achieved either.
5. The unit runs at least once a month. If it is shut down for more than six months, remember to change the engine oil before starting it. This is to avoid blockage of the chiller.
